NTTD STATES BERNHARD SCHEITHAUER, OF HALLE-ON-THE-SAAIE, GERMANYf eALvANlC BATT-lam() SPECIFICATION foi-ming part of Letters Patent No. 396,342, dated January 1889.

Application tied December-5,1887. Striano. 257,013. (No model.; m.:

'T0 all whom t may concern-l4 l Be it known that I, BERNHARJ; Seurin- HATIER, a subject of the Emperor of 'Germany,

and a resident of llalle-on-the-Saale,Gew

many, haveinvented a new and. useful Improvement in Primary Batteries, of which the following is a specification.

This invention relates to galvanie batteries, and its-object is to produce a battery capable of giving' a constant current and one which shall at the same time be inexpensiye in maintenance.

The improvement relates, principally, to the prevention of polarization by. causing the hydrogen collecting on the carbon plates to be removed by means of chlorine gas, the latter combining with hydrogen to form hydrochlorie acid, which is also utilizedlbrthefurther production ol chlorine, in the manner described.

rlhe accompanying drz'uvings illustrate in several forms batteries, all based upon the improvement above described.v

Figure .l is a vertical section ot a one-cell battery with diaphragm. Fi g. 2 is a similar view of a two-cell battery with diaphragmg Fig. 3, a single-cell battery without diaphragm; Fig. l, a series of cells arranged without diaphragms in the manner of a vol! taie pile. y A is a jar, of glass, porcglain, earthenware, or the like, sueh as is usually employed l'or the cells of galvanie batteries, but 'preferably of somewhat,greatbr depth ,in proportion to its breadth.

l is a pla-te or plates, ol' carbon, copper, or

other metal or material usuallyemployetltor negative plates.

C is a pillar or positive plate.

D is -a'd'iaphragm or` porous jar surrounding the zine plate in the known manner. The positive and negative plates and diaphragm aforesaid are` supported upon a perforated wall, E, extending across the jar A and dividin g the lattc'r into two parts. R isa thistle-tube exi ending downward into the jar A, and terminaf ing at a short distance below the wall E. The vlower part of the jar A, below the wall E, is filled with a 'mixture ot chloride of lime, common salt, and manganese. The space about the negative plate is packed plate ziue,.formin'g thle' witlrasbestus, m., and the space about the zine plate is lled with Water. The space about the negative plate is also preferably hermetie'ally closed above by disks or plates a, of vuleanite or the like.

In practice I prefer to `make the wall E as a part with the diaphragm D in a simple element,-as shown in Fig. l, and' to leave that part ofthe wall E which is situated under and forms a bottom to the cell formed by the diaphragm l) unperforated, to prevent the direet connection between this portion of the cell and the mixture below the wall E.

In the battery shown in Fig. 2 the trough A is made of sufiicient size to contain all the cells, and the lower part thereof is filled with the arm-@mido ture. The wall Ewill then extend in one piece across the whole extent of the trough, a-nd the cell-walls A and diaphragms D will be formed without bottoms and eausedfto rest uponl the wall E. To-taeilitate the filling ofthe mixture into the lower part of the receptacle A', the wall thereof may be'provided with a comparatively large opening closed by ascrew-plug,12,01

the like. A tap, d, n lay likewise be arranged for-drawing oft" the liquid from the trough.

The battery shown in Fig. 3 is a single cell frthout diaphragm. In this batterythe spaces between the plates are paeked'with asbesius, as well as the space about the carbon plate, and the asbestus is caused toJ extend downward more or less into the bottom of the jar A-that is to say, a'sbestus isplaced therein betweeii-portious ot' the mixture before described yin eorreslumdenee with the asbestus.abitve/fthe wallv lt; also, inthe battery shown in Fig. with7 the pl..

being' a: waged inpairs, with llayers ot' asbostus liber between eaeh pair,-

said layers extent'ling downward into vessels F, containing water.

`'L diaphra ms are dispensed 9o For bringing the battery into action hydrochlorie acid is pouredY into the thistle-tube R, and; thus into the lower space oi' the trough A or jar A, where it acts upon the mixture therein contained to form chlorine gas, the said ascending among the asbestus lfiber about the negative plates. The hydrogen -fol-mingen said plates is thus brought into intimate contact' with the chlorine, and combines therewith io form hydrochloric acid,

which sinks into the lower part of the vessel and acts upon the mixture therein. Thewaterinoistens the asbestus, and, becoming more or less acid from the ,dissolved hydrochloricacid gas foi-med, reacts on the zinc. l

Having described my invention, I claim and desire to lecfcure by Letters Patente-'- 1. ln a galvanc batter the combination of a receptacle havingahorizontal perforated wall, negative andpositire plates above Said wall, a1 l ll a mixture adapted to evolve chlorine below said wall, with a liquid or liquids suitable for exciting said batter)7 and production oi chlorine, substantially as set forth.

2. The combination of a receptacle having a horizontal perforated wall, negative and positive plates above said Wall, asbestus liber about the negative plate or plates, and amixture adapted to evolve' chlorine below said.

wall, with liquid or liquids for excitinr said battery and. production of chlorine, substantially as and for the purpose set forth.

In testimonywhereof I have signed this speciication in the presence of twn .Quhgnw'w'vf w# ness'es.
